Share time together, catching up on the latest over a cup of tea or a meal.
"Special" is not quite the right word.
Time shared signals to me that the liking is mutual.

Hug me, feed me, thank me, or give me money/gifts.

Bring me food!

Pad my shoulder and a thumb up and say you are a good person😌

Well, you see, when a man friend really loves a woman friend ... And that's how babies are made.

Idk I don't know any
